A gate that won’t open, grinds when it moves, or sags hard against the driveway isn’t a small annoyance in San Antonio. It locks you out, leaves the property exposed, and puts stress on the opener motor every single cycle. Calder Gate Repair San Antonio fixes driveway and pedestrian gates of all types, from heavy wrought iron to wood and tube steel, usually within one visit. We’re the dedicated gate repair shop inside the Relay Home Co. family, founded in 2009, and every tech who arrives is background-checked and in uniform. Call (361) 314-4803 any hour and a live person picks up, not a bot.

Driveway Gate Repair
Driveway Gate Repair is the fix for any gate that blocks vehicle access, whether it’s sagging on its hinges, stuck partway open, or refusing to close after you enter or leave. The usual culprits in San Antonio are shifted concrete posts from our expansive clay soil, tired opener arms, and steel that has rusted where sprinklers strike it every morning. Calder Gate Repair San Antonio handles all of it, from re-hanging and re-welding to replacing limit switches and rebuilding post mounts. Most driveway gate repairs in our area run $180 to $600 before parts, and you’ll have a written price before we turn a single bolt.
Post and Hinge Work
When the gate drops or scrapes, the post or hinge has usually moved. We re-set posts, handle Hinge & Post Repair, and sometimes re-core the post with steel so the same failure doesn’t return next season.
Opener and Track Alignment
If the gate jerks, beeps, or stops mid-travel, the opener and track often aren’t talking. We check the arm geometry, the track wear, and the opener force settings, then correct all three in one visit.
Styles & brands we work with


Gate Welding
Gate Welding is structural repair for metal gates, not a cosmetic patch. When a weld cracks at a picket, a hinge tears off the frame, or the bottom rail rots through, the gate needs heat and new steel, not a bolt-on plate. The team at Calder Gate Repair San Antonio welds on-site with mobile rigs, so your gate never leaves the property. Depending on the location and amount of steel, welding repairs in San Antonio typically run $150 to $700, and you’ll see the price in writing before we spark an arc.
Crack and Tear Repair
Gate frames crack at stress points where the opener pushes. We grind out the damaged area, weld in fresh steel, and often add a gusset so the stress moves off the weak point.
Replacing Rotted Sections
San Antonio sprinkler water and humidity eat gate bottoms fast. We cut out the rotted rail or picket, weld in matching new material, and coat the repair to match the surrounding finish.
Commercial Gate Repair
Commercial Gate Repair keeps apartment complexes, storage facilities, HOAs, and business yards running on schedule. A down gate at a San Antonio property doesn’t just annoy residents, it can stall deliveries, block emergency access, and create a liability if the Automatic Gate Repair safety edges stop working. Calder Gate Repair San Antonio works on slide gates, swing gates, barrier arms, and the operator systems behind all of them, including Viking and DoorKing units we see constantly in local commercial lots. Commercial jobs run from $300 for basic operator faults to $2,500 or more for full track and gate overhauls, always with a written price agreed before work begins.
Access Control Integration
A gate that opens for no one has usually lost its connection to the keypad, card reader, or phone entry system. We fix the operator side and verify the access hardware fires the gate correctly before we leave.
High-Cycle Gate Maintenance
Gates that cycle hundreds of times a day wear chains, rollers, and gearboxes fast. We stock common parts for DoorKing and Viking operators and replace worn components on a schedule, not after the failure.
Iron Gate Repair
Iron Gate Repair covers the heavy, ornamental gates common in Terrell Hills, Alamo Heights, and older San Antonio neighborhoods. These gates are beautiful and brutally heavy, which means any sag, cracked weld, or rusted hinge gets worse quickly and wears out the opener trying to move the added friction. Calder Gate Repair San Antonio re-hangs, re-welds, and rust-treats iron gates so they swing cleanly and close flush again. Expect $200 to $800 for most iron gate repairs, parts included on standard fixes, and a written line item price before work starts.
Rust Treatment and Preventative Coating
Surface rust becomes structural rust faster near San Antonio sprinkler overspray. We remove scale, treat the oxidized steel, and seal the joint or edge so moisture stops eating the metal.
Re-hanging Heavy Gates
An iron gate that drags or won’t latch usually needs Gate Realignment or has worn hinge bearings. We correct the post, replace the hinge hardware, and balance the gate so the opener isn’t fighting the weight.
Sliding Gate Repair
Sliding Gate Repair addresses the cantilever and rolling slide gates used on many San Antonio driveways and commercial lots, the ones that ride on a track and glide sideways instead of swinging. The common failure points are worn roller wheels, bent track from vehicle strikes, and misaligned chain drives that make the gate shudder instead of glide. Calder Gate Repair San Antonio replaces rollers and wheels, straightens or replaces track, and re-tensions the drive chain or belt. Most sliding gate repairs in our service area land between $220 and $800, with the final number written down before we touch anything.
Roller and Wheel Replacement
Worn rollers cause the grinding sound and the jerky movement. We replace the entire roller set and check the track level so the new wheels roll clean instead of binding.
Track Straightening and Replacement
When a car bumps the gate or the ground shifts, the track gets a wave in it. We straighten or splice in fresh track and anchor it so the gate travels smooth at both ends.
Wrought Iron Gate Repair
Wrought Iron Gate Repair focuses on decorative steel gates made from hot-formed iron, often custom designs you can’t just buy off a shelf. When a scroll cracks or a picket separates from the rail, the repair has to preserve the original look, not just hold it together. Our San Antonio welders repair broken scrolls, replace missing pickets, and reinforce frames without changing the gate’s character. Wrought iron work costs more than plain tube steel because it’s slower and requires matching pieces, typically $300 to $900 per repair, always quoted in writing.
Ornamental Matching
A missing finial or broken scroll changes the whole gate’s look. We source or fabricate matching ornamental pieces so the repair disappears into the original design.
Frame Reinforcement
Beautiful gates often have thin frames that flex under opener load. We add internal steel reinforcement hidden behind the ornamental work, strengthening the gate without changing its face.

Metal Gate Repair
Metal Gate Repair is the broad fix for steel and aluminum gates, from simple tube steel driveway gates to modern aluminum slat gates common in newer San Antonio subdivisions like Cibolo and Bulverde. The steel versions crack and rust, while aluminum versions more often suffer hardware failures at the hinges and latches. Calder Gate Repair San Antonio works both materials, replacing sections, welding cracks, and upgrading hardware so the gate moves properly. Metal gate repairs generally run $150 to $650 depending on the material and damage, with the full price written out for you before any work begins.
Steel Frame Repair
Tube steel gates crack along the bottom rail or at the opener mount. We weld the crack and add a brace so the repair outlasts the original weld.
Aluminum Hardware Upgrades
Aluminum gates don’t rust, but their hinges and bolts do. We replace seized or corroded hardware with coated fasteners made for outdoor exposure.
Wood Gate Repair
Wood Gate Repair handles the cedar, pine, and redwood gates found on older San Antonio homes and ranch-style properties in Scenic Oaks and the hill country edges. Wood moves with humidity, warps, and rots at the bottom where rain splashes back up. A sagging wood gate is usually the frame, not the hinges, and a gate that won’t stay latched has often shifted too far to catch. Calder Gate Repair San Antonio braces or rebuilds wood frames, replaces rotted boards, and re-hangs the gate square. Expect $150 to $500 for most wood gate repairs, quoted in writing before work starts.
Frame Bracing and Squaring
Wood gates sag when the diagonal brace fails or was never sized right. We add proper bracing, square the frame, and adjust the hinges so the gate swings level.
Rotted Board Replacement
The bottom and lower rails go first. We remove the rotted material, replace with matching or treated lumber, and seal the end grain so water stops wicking upward.

AfterBrands We Service
On the operator side, our techs are factory-familiar with the units San Antonio homes and businesses actually run. We service Viking operators daily, the workhorse for commercial slide gates, and we stock their common boards and limit components on the truck. DoorKing is another staple we see in apartment and HOA settings, and because they’ve changed control boards over the decades, we keep the older diagrams on hand and the newer parts in stock.
Ghost Controls and Elite round out the residential side we repair often in the San Antonio area, particularly on newer aluminum and tube gates where homeowners have added a smart opener. Our service vans also carry parts and know-how for LiftMaster, FAAC, BFT, Linear, and Mighty Mule. If you have one of those, we can likely fix it the same visit. If you’re not sure what brand is on the gate, describe the keypad or remote when you call and our live tech support can usually identify it.
Signs You Need a Pro Right Now
- The gate shudders or jerks while moving. That’s almost always a worn roller, a bent track, or an opener gear that’s stripping itself. Running it like that for another month often turns a $200 roller job into a $700 operator replacement.
- You hear grinding from the opener. The gears inside the motor are chewing themselves. Every cycle makes it worse, and the repair is cheaper done now than after the housing cracks.
- The gate stops halfway and beeps. The safety sensors or limit switch have lost their setting. It usually means the gate won’t close fully, so the property stays open until it’s fixed.
- The gate sags visibly or drags the ground. Hinges or posts have shifted. The opener is now pulling against that extra resistance every single cycle, and motors burn out from this.
- The automatic reverse isn’t working. This is the dangerous one. If the gate doesn’t reverse when it meets resistance, you have a safety system failure that needs immediate attention before someone gets pinned.
Our Process, Step by Step
- 1
Call and talk to a human, any hour. You dial (361) 314-4803 and a live person answers. We ask what the gate is doing, what brand the opener is if you know it, and what city you’re in. Then we schedule a specific arrival time you can track live.
- 2
We diagnose on-site and show you the numbers. The tech finds the fault, explains it in plain language, and writes out the repair price before any work starts. The number on that paper is the number you pay, parts and labor included unless you add work later.
- 3
We repair the gate with the right parts. We stock common OEM components for DoorKing, Viking, Ghost Controls, and other major brands. If something’s not on the truck, we tell you the exact day we’ll return so you’re never left wondering.
- 4
We test the full cycle with you watching. Open, close, safety reverse, keypad, remote, and any vehicle sensors all get run through together. You see the gate working correctly before we call the job done.
- 5
You get the invoice and the 365-Day Done Right Promise in writing. We text or email the invoice, the before and after photos, and the written guarantee. If the repair fails within 365 days, we return at no charge. That’s the Relay Standard and it’s not optional.
How Much Does Gate Repair Cost in San Antonio?
A typical gate repair in San Antonio runs $180 to $650 for most residential fixes, and the majority of San Antonio homeowners pay between $200 and $400 for common issues like hinge re-alignment, opener limit adjustment, or a welded cracked joint. Simple service calls and Lock Repair land near the low end, while full operator replacements or major structural welding reach $1,500 or more on commercial slide gates and longer runs. Here’s what shapes the price: the type of gate (wood is usually cheapest to repair, ornamental wrought iron the most labor-heavy), the opener brand and part cost, and whether the damage is isolated or has spread to the track, hinges, and frame.
What affects the bill most is time. A simple hinge job may take 45 minutes. Straightening a bent slide track and replacing four rollers might take three hours. You can avoid overpaying by paying attention to the gate the first time it scrapes, shudders, or starts beeping, because ignoring those signs turns mechanical fixes into structural ones. Our free estimate includes the diagnostic, the repair plan, and a written price. You know the exact number before you approve a single step, and if you decide not to proceed, you owe nothing.
